The Swash is an easy-wearing oversized frame designed to provide excellent coverage and increased field of vision. Despite its size, it wears lightly thanks to our proprietary bio-based nylon, which is both lighter and stronger than oil-based polycarbonate plastics. Soft, grippy contact points on the nose and temples keep the featherweight frames from floating away, while Fresh Eyes™polarized lens technology blocks blue light to keep eyes free from strain and fatigue to make long days on the water even more enjoyable.
